MACHINE FOR PO'INTING WIRE NAILS.

SPECIFICATION forming part of Letters Patent No. 350,837, dated October 12, 1886.

I Application filed January 5, 1836. Serial No. 187,670. (Nomodch) T on whom it may conceive:

Be it known that I, ARTHUR NEWTON, of Boston, in the county of Suffolk and-State of Massachusetts, have invented certain new and useful Improvements in Nailing-Machines, of which the following is a specification.

This invention relates to the manufacture of nails from a continuous wire, and has especial r0 continuous wire supplied to the machine and drive them into or through'boot or shoe soles.

The invention consists in themeans hereinafter described for forming chisel or wedge shaped points on wire nails. i I 5 The invention also consists in an improved organized nailing-machine, in which are combined a cutter fortrimming a portion of a wire to form an approximate point at. its end, means for feeding and meansfor severing the wire and carrying forward thesevered section to the'driver, the arrangement being such that i the cutter trims off a portion of the wire beforeit is fed and severed and carried under the driver, all of which I will now proceed to describe. I

In the accompanying drawings, forming a part of this specification, Figures 1 and 1 are side views of a piece of wire, showing my improved methodof pointing nails. resents a longitudinal section of an organization of devices for forming wedgeshaped points on wire nails, said organization being shown as a part of a boot and shoe sole nailing machine. Fig. 2 represents a section on line y Fig. 1. Fig. 3 represents a similar section at a different stage of the operation. Fig. 4 represents a section on linear m, Fig. 2, showing the'pa'rts in the same position as in Fig. 3. Fig. 5 represents a section on line m m, Fig. 2. Fig. 6 represents a section 'on line y. y, Fig. 3, showing the parts in the same position as in Fig. 4. Fig. 7 represents a 1ongi'-- looking upwardly.

Fig. 11 represents a view like that shown in Fig. 10, afterthe point has been formed. Fig. 12 represents a section on line at w ,-Fig. 10. Fig. 13 represents a section on line 9 p Fig. 11. Fig. 14 represents a vertical section of a nailingmachine to which my improvements are applicable.

.The same letters of reference indicate the same parts in all the figures.

My improved method of forming chisel or wedge shaped points on wire nailsconsists in first bending the wire 1? near the end to be pointed, as shown in Fig. 1*, thus giving one side of the wire a beveled surface, 2, having the inclination required for one side of the wedge-shaped point, and then cutting or trimming off the wire diagonally across the bent portion, as indicated by the dotted line in Fig. 1, to form the opposite side, 3, of the wedgeshaped point, as shown in Fig. 1, so that the point is formed partly by bending and partly by cutting.

The best means that I have devised for carrying this method into effect are shown in Figs. 1 to 6, which Iwill first describe, said means being shown as a part of a boot and shoe sole nailing machine of the class shown in Letters Patent of the United States No. 243,601, granted to me June 28, 1881. A side View of said machine is shown in Fig. 14..

H represents a fixed frame orcasing, having an orifice or fixed wire-guide, K, to receive and guide the wire P, and a guide or way in which a'slide, ,L, "is adapted to reciprocate Said slide has an-orifice, M, 0 which at a given point in the movement of the slide registers with the wire-guide K in the caSing'H, "and receives the wire 1?, as shown in Fig. '1. Theslide is reciprocated by any suitable means, (forbxamplasnch as are shown for reciprocating the slide L in the abovenamed patent,) and in moving forward in the" direction indicated by the arrow in Figs. 1 and 2 co-operates with a block, a, which is temporarily moved to the position shownfinroc Figs. 1, 2, and 4, so as to bear on the rear side of the wire, the slide L and block a constituting shears, which are caused by the forward movement of the slide to sever anail, P',which has been previously pointed from the wire P, said nail being carried forward by the slide until it stands over an orifice, n, in adeliver ing-nose, N, formed on the fixed frame or cas ing H. Theslide is held in this position while a driver descends through it and through the orifice n and drives the nail into a boot or shoe presented to the nose N, as shown in my former patent.

0 represents a trimming-blade attached to the slide L, and having its cutting-edge behind the orifice M in said slide. Y

11 represents a block fitted to slide in the frame or casing H beside the block a. Said blocks wand d are reciprocatedindependently by any suitable means, so as to operate as fol-' lows: After the wire has been inserted 'in the slide L, as shown in Fig. 1, the block ctis moved outwardly, so as to bear against the rear side ofv the wire, as shown in Fig. 2. After the nail has been severed by the forward movement of the slide, as previously described,the

block a is withdrawn from behind the wire,

and before the cutter 0 reaches the wire the block d is moved forward against the wire, and thus caused to bend the latter diagonally across the path ofth-e edge of the cutter, as

shown in Fig. 6, said path being ther'eindicated by dotted lines. The end of the'block d is beveled, as shown, so that it gives the side of the wire against which it bears the incline 2, which forms one of the sides of the wedgeshaped point, while the edge of the cutter is oppositely beveled, so that when it reaches the wire it trims off a part of the bent portion, and in so doing forms the other side, 3, of the wedge-shaped point,- Figs. 1 and 1, the point being thus completed. After the cutter has acted on the Wire the block d is moved back, asshown in Figs. 2 and 5, and when the slide L returns to the position shown in Fig. 1, after delivering the last nail to the driver, the pointed end of the wire is fed into the slide by the mechanism shown in Fig. 14, and fully described in my former patent, or any other suitable feed mechanism, and another nail is severed by the next forward movement of the slide. In this way the wire is pointed afterthe severing of each nail.

The mechanism for feeding the wire P, as.

described in my former patent and shown in Fig. 14, is composed of a pair of plates or feed feed the wire into said block. The frame 0 is provided with a vertical arm,f, adapted to slide in a socket in the frame A. The frame a is pressed by a spring, against the cam G on the driving-shaft, and is therefore reciprocate vertically when the shaft rotates.

72. represents a wedge located on the driverbar, which bar is also reciprocated vertically by means of the cam F, a stud, I from said bar bearing'on the cam, and a spring adapted to force the driver-bar abruptly downward when the cam passes from under the stud 7c.

The wedge h is so arranged and the driver-bar is so timed in its movements that when the feed-jaws arise the wedge will also rise, and at the same time insert itself between and separate the jaws a, so that during their upward movement they will not move the wire. \Vhen the jawsahave completed their upward movement, they descend before the driver-bar,

so that the wedge remains behind, and the operator desires to change the length of the nails, he moves the wedge Z in one direction or the other, thereby permitting the arm f to descend more or less. The wedge Z may be moved by the operators foot through a treadle and suitable intermediate mechanism, so that the length of the nails may be varied while the machine is in operation.

I have shown in the present instance as the means for operating the blocks ad two slides,

h i, fittedto reciprocate in guides in the easing H, and having studs jla at their inner ends entering diagonal slots Z min the blocks a d. The slides h z are reciprocated longitudinally too by cams or other-well-known means, and their studs j k, acting on the sides of the slotsZ m, reciprocate the blocks, as will be readily understood. A

In the organization shown in Figs. 7 to 13, the cutter 0, instead of being attached to the slide L, is attached toor framed on aseparate bar, 0, fitted to slide in agnide in the casing H, above the slide L, and the wire-bending block or die 61 is moved against the wire by an incline or cam, p, fitted to slide in a guide in the casipg H parallel with'the cutter-bar 0. The operation of these devices is substantially the same as of those first described. The wire is severed by the co-operation of the slide 10 and the bending die or block (1, the latter standing in the position shown in Fig. 7 when the slide commences to move forward. After the wire is severed the bars 0 1) move forward simultaneously, the cam 13 moving in advance of the cutter,and.causing the block dto bend thewire, as shown'in Fig.12, before the cutter reaches it. The cutter then trims the wire and completes the point, as shown in Figs.'11 7 and 13. When the bars 0 p have moved back after the completion of the point, the block d, beingunsupported from behind, yields to the downward movement of the wire when the latter is fed into the slide L, and is thus restored to the position shown inFig. 7.

It will be seen that the portion of the wire which is severed to form the nail is shaped or trimmed hythe cutter before it is fed into the nail-receiving orifice M of the slide L, and

tl:1erefore before it is severed from the main wire by the movement of said slide which carries the completed nail under the driver. The

-combination of devices essential to the accomplishment of this result does not necessarily include the bending devices.

While my invention is intended mainly for boot and shoe nailing machines it is obvious that it may be used for forming poiuts'on other kinds of wire nails.' v, llllll v,

The wire shown in this instance isrectangular, but any other form of wire may be used.

It is obvious that the order of the cutting andbending operations may be reversed, the cutting being performed before the bending.

In testimony whereof I have signed my name to this specification, in the presence of two sub scribing witnesses, this 2d day of January, 1886. t
